Abstract

A liquid crystal display of the present invention comprises a display portion having two opposed insulating substrates (an electrode substrate (1) and an opposed substrate 2) holding a liquid crystal layer to form a plurality of display elements, wires (3a) formed on at least one of the insulating substrates, for supplying signals to the plurality of display elements, a driver LSI (6) provided in a peripheral portion of the insulating substrate, being connected to terminals of the wires (3a, 3b) to drive a plurality of display elements, and a conductive film pattern portion formed on the wires (3a) in the peripheral portion of the insulating substrate with a first insulating layer interposed therebetween. With this constitution, a liquid crystal display which allows inspection of output signals of the driver LSI in a failure analysis, without extending wires or exposing electrode portions connected to the wires and a method of inspecting the liquid crystal display are provided.
